Looking to buy some new wheels for my 2015 and am looking for info on backspacing, offset, etc. I dont want to get new wheels and have issues with inside clearances or have them stick way far out past the fenders.

Ive done some google searches but it keeps showing the stock wheel size being 20", I have 17" stock wheels on my truck.

I'm pretty sure that the rims have a +42 offset and the 20 is 9" wide. The 17 may be only 8 but it's likely 9. If you take off a wheel it should show all of the dimensional Info cast inside the rim
